Washroom sealing in Brondesbury, done properly
Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. We work on accessible toilets and changing rooms, showers, trays and wet room floors and IPS panels and cubicles, and what we’re called in for most is failed joints along IPS and cubicle panels and stained sealant around pans and urinals. A single leaking joint is often how a building in Brondesbury first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Many London buildings can’t close every toilet at once. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What the job involves on each surface
Kitchens and tea points
Kitchen work can be phased around service. Tell us your site hours and access windows and we’ll plan around them.
Wet-room floors and floor-to-wall joints
Wet-room floors and the joints where flooring turns up the wall need to stay sound. Floor perimeters and sealant joints near drains are resealed.
Maintenance after handover
Once the work is signed off, these steps help:
- Make sure washroom ventilation is running
- Report split joints at trays and basins early
- Respect the cure time before reopening each room
- Inspect washroom sealant regularly
Ventilation is half the battle. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.
A split joint at a shower tray can leak for a long time before anyone sees it. By then, other trades may be needed as well, so reseal when you first spot a split.
Wet areas in Brondesbury’s workplaces
London offices and hotels typically can’t close all their washrooms at once, so resealing goes floor by floor, agreed with the facilities team. Brondesbury has plenty of hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping.
Office washrooms on sites such as The Quadrant Business Centre, under half a mile to the south of Brondesbury, are in use all working day, so resealing is phased to keep some open. Toilets at colleges like City of Westminster College, 1.4 miles to the south-east of Brondesbury, take heavy use from students and staff alike. Halls of residence and teaching buildings at universities such as Imperial College London (2.3 miles south of Brondesbury) are easiest to reseal during vacations.

Questions we are asked in Brondesbury
Can work at a site such as Imperial College London fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Will our hotel in Brondesbury need to close for the work?
In the majority of cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we will plan around them.
Will all the toilets be closed at once?
The work is phased so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
How do I request a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or email drawings and photos. Include photos or drawings if you have them.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Hollow tiles or loose panels behind the joint
- Leaks through tanking or membranes below the finishes
- Condensation from failed extract fans
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly.

From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Planning a London job such as one in Brondesbury starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
What we need from you
- Make sure the joints can be reached
- Let us know about inductions and permits
- Point out parking and an unloading spot

What happens if it’s left?
When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Getting scaffold, permits or access booked in Brondesbury takes effort, so it makes sense to deal with every failing joint while access is in place.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
